TRACK-SANDER.

I sanders, such as are used on locomotives and particularly to that type of track sander, long well known and in common use, in which the sander is provided with a sand discharge passage through which the sand passes from a sand dome or reservoir to the rails, the passage being dipped between its ends to provide a sand trap from which the sand is blown out when needed, by a jet of air or steam from a nozzle projecting into the passage adjacent the bottom of the sand trap portion.

The object of the invention is to provide a simple and satisfactory construction less liable to become clogged by lumpy material mixed with the sand, than is the case with the arrangements heretofore in use, and from which, in case of clogging, the objectionable material may be removed more quickly and easily than has been possible with the sanders heretofore in use. This accomplish by enlarging the sand passage of the sanding mechanism between the reservoir sand trap portion thereof to form a chamber substantially larger in cross section than the remainder of said passage and by also providing a clean out opening from said chamber larger in cross section than the portion of said sand passage beyond the tra The various features of novelty that characterize my invention are pointed out particularly in the claims annexed to and forming a part of this specification.

For a better understanding of the invention and the advantages possessed by it, however, reference may be had to the accompanying drawings and descriptive mat-' ter, in which I have described one of the forms in which the invention may be embodied.

dome or reservoir and attached sander mechanism; Figs. 2 and 3 are sect-ions taken on 3 of Fig. 1, respectively, and Fig. i is a rear end elevationof the sander mechanism.

In the construction shown in the drawings, A represents a sand reservoir, as the dome of a locomotive, and A the sand discharge port or passage in the wall thereof.

B .represents the sand trap containing a blast nozzle supporting-member. The member B is formed with a channel or sand passage 0 which registers at one end with the discharge port A and is adapted to be connected at the opposite end to the usual pipe, not shown, for conducting the sand to the track .rails. lVithin the member B the channel C- is given a dip, to provide a sand trap at C D represents a blast nozzle extending into the passage C adjacent the bottom of the dip thereof; C and C represent clean out openings formed in the member B and E and E represent screw plugs normally closing these openings.

F represents the usual removable and re- ;newable cap against which sand fromthe that the discharge port A from the reser- ..voir and the clean out opening C and plugs E, are enlarged to correspond with the e11- larged cross section of the chamber C These differences result, however, in substantial and highly beneficial differences in operation between my improved sander and those before known. Heretofore, the sand passage or channel, in a sander of the type illustrated, has been, in practice relatively small in cross section throughout its length. The reduced cross section of this passage has been due in part, to the desire to keep the apparatus of relatively small bulk, but principally to the fact that if this passage is made too large the sand is less effectively discharged through it by the blast. I have found, however, that I may enlarge the cross section of the passage back of the blast nozzle without reducing the efliciency of the nozzle as a sand ejecting device, and that by enlarging the passage back of the sand trap, the trouble caused by lumps and foreign objects in the sand, is greatly diminished. With the passage port-ion C enlarged and port A foreign objects or lumps in the sand which would otherwise tend to collect in the reservoir at A and clog the latter discharge orifice, pass into the channel enlargement or chamber C. On account of the immediate proximity of the chamber C to the nozzle D, such lumpy or foreign matter, passing into the chamber C is less apt to clog the apparatus than is the case where they collect at the inlet end of the discharge orifice from the sand reservoir, and furthermore, these lumps or foreign matter may be much more readily removed from the chamber C through the clean out openings C and C and particularly through the enlarged clean out opening C than is possible where the lumpy or foreign material collects within the sand reservoir or even in a sand channel portion in the sander proper of the cross section of the passage C in front of the blast nozzle D. At the same time, the improved sander is but little more bulky than those heretofore used.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. In a track sander a member formed with a sand passage which dips between its ends to form a sand trap, and a blast nozzle projecting into said passage adjacent the bottom of the sand trap portion thereof, said member having a portion of said passage at and leading away from its inlet end enlarged to provide a chamber which is substantially larger in cross section than the portion of said passage at the outlet side of the blast nozzle, and in which material tending to clog the sander may collect, and being provided with a normally closed clean out opening through which such material may be removed.

2. In a track sander a member formed with a sand passage which dips between its ends to form a sand trap, and a blast nozzle projecting into said passage adjacent the bottom of the sand trap portion thereof, said member having a portion of said passage at and leading away from its inlet enlarged to provide a chamber, which is substantially larger in cross section than the portion of said passage at the outlet side of the blast nozzle, and in which material tending to clog the apparatus may collect, and being provided with a normally closed clean out opening through which such material may be removed, said opening being also substantially greater in cross section than said portion of the sand passage at the outlet end of the blast nozzle.

3. Track sanding mechanism comprising in combination a sand reservoir provided with a discharge port A a member B, formed with a sand passage C, which dips between its ends to provide a sand trap portion C and a blast nozzle projecting into said passage adjacent the bottom of the sand trap portion C said member B being secured against said sand reservoir with one end of said passage C in register with said discharge port A the portion of said passage C between the sand trap portion C and.

the reservoir port A as well as the latter, being substantially larger in cross section than the portion of the passage C beyond the blast nozzle, whereby lumps or foreign objects in the sand tending to clog the ap paratus collect in the chamber C formed by the enlarged portion of the passage C, said member being provided with a normally closed clean out opening C leading from said chamber C and also substantially larger in cross section than the portion of the channel C in front of the blast nozzle.
